In general wallet design, vague expressions like "somehow nice" or "cute form" are often used. SOLA products do not have such subjective decorations. The sharp outlines of Tenuis and Tynd, reminiscent of envelopes or paper, are all based on meticulous theory and calculation.
Generally, containers designed for storing things tend to be rectangular in shape. Round and curved shapes result in wasted storage space and are considered superfluous designs. However, curves can be useful in areas that people touch inside the container.
And often, the designs that emerge from those calculations turn out to be just right. While "calculating design" might sound like an interesting expression, this is actually how SOLAHANPU products are created.
